Scanmaskin Scan Combiflex 450NS Floor Grinder

Who should use the Scan Combiflex 450?

The Scan Combiflex 450NS is a powerful concrete floor grinder that features a built-in water tank. It’s ideal for both wet and dry grinding on small to mid-size jobs or building remodel applications.

The Scan Combiflex 450NS is part of the family of 18-inch grinding and polishing machines from Scanmaskin. It is great for light coating removal as well as wet and dry grinding and polishing of concrete, terrazzo, and natural stone surfaces.

Although conditions will vary greatly from job to job, most contractors have been pleased to report production rates of around 320 to 540 square feet per hour.  

What are the power options?

The Scan Combiflex 450NS is available in a 230-volt, single-phase configuration.

It will work with between 208 to 240 volts, giving you flexible power options for fast and easy job setup.

Is it easy to use?

When it comes to using the machine, the controls couldn’t be simpler. Just press the green button to start the machine, and the red button to stop it.

The unit also features an emergency stop button as an extra precaution. The emergency stop button will remain depressed until the operator turns it slightly clockwise to pop it out.

Simple twist knobs control the direction and speed of the spinning heads. You can easily switch the direction of the grinding heads to ensure longer life and even wearing of your diamond tooling. This maximizes their use and saves money in the long run.  You can also adjust the speed between 300 to 1,100 RPMs, letting you dial in the perfect cutting rate. 

The water tank on the 450NS also has a flow control valve, which lets you adjust the water flow to match the grinding needs of the job.

Don’t I need more horsepower?

When it comes to choosing a grinding machine, many contractors mistakenly think that horsepower is most important. Don’t be fooled.

Scanmaskin engineers discovered that most grinding equipment is terribly inefficient. They rely on tension belt systems that need to make up for the loss in power by having larger motors that produce more horsepower. But because of their inefficient design, all that extra power isn’t directed at the floor – it’s also directed at the operator who has to lean against the machine and fight it as it kicks and bucks.

Scanmaskin equipment features a highly efficient patented drive system that uses less horsepower but delivers more torque on the floor – not on your hip!

Why do you make such a big deal about the drive system and grinding heads?

The unique free-standing planetary drive system of the Scan Combiflex 450NS requires very little maintenance and provides improved torque for great grinding and polishing performance. Simply put: it’s superior engineering that delivers better results on every job.

The 3-head planetary system holds up to 9 tools. Unlike other systems that require a screw driver, Allen wrench, and hours of struggle to attach tooling, the Scan Combiflex lets you easily tap on and tap off your tools.

Another unique engineering element of the Scan Combiflex 450NS is that the heads feature spring steel disks, not rubber flex systems like most other grinders on the market.

After thorough side-by-side testing, Scanmaskin engineers discovered that the spring steel disks were far superior to the traditional rubber flex systems found on most other grinders. They provide increased durability and better, more consistent grinding. They can be configured to increase or decrease head flexibility as well, something rubber flex discs can’t do.

Spring steel disks are perfect for any type of grinding application, from aggressive surface prep to providing that fine finishing polish.

What maintenance will this machine need?

The Scan Combiflex 450NS is designed to not only be durable, but to also require very little daily maintenance.

We recommend opening up the control box before each job to check for accumulated dust. If any dust is present, use a moisture-free air system to blow it out. This helps keep the motor clean and prolongs the life of the machine.

We also recommend replacing the belt every 2 years or 5,000 hours. However, these belts are rated for up to 10,000 hours, so this is simply a precautionary recommendation that will help reduce maintenance costs and downtime in the long term.

When it comes to changing belts, by the way, Scanmaskin makes the process incredibly easy. Unlike other grinders that may take 6 to 8 hours or even require a professional mechanic to change the belt, Scanmaskin belts can be replaced in as little as two hours.

Is it easy to transport?

The Scan Combiflex 450NS has large, solid wheels, so maneuvering the unit around the job site or up and down a ramp is a breeze.

How tough is this machine?

When we describe this machine as durable, we’re not exaggerating.

Unlike other units that feature plastic or fiberglass parts, the Scan Combiflex 450NS is made from solid steel – right down to the dust shroud. This unit resists dents, chips, and cracks, ensuring that it far outlasts the competition.

What about dust control?

Dust can be a major issue for other systems when it comes to dry grinding applications, but not for Scanmaskin equipment. 

All Scanmaskin floor grinders feature a dust shroud made from solid steel. You won’t find duct tape on a Scan Combiflex unit. Unlike other grinders with shrouds made from plastic or fiberglass, our dust shrouds won’t chip or crack, and they do a far superior job of controlling dust and debris.

The Scan Combiflex 450NS also has an adjustable thick rubber dust skirt, so you can position it flush against the floor, creating a better seal.

Lastly, the unit features a dual vacuum port for more efficient dust collection.

The combination of these features makes for virtually dust-free grinding and polishing. The result is a cleaner work area that takes less time to clean up and is safer for the operator and building occupants.
